IMPORTANT: The SureSine Inverter is designed for converting DC power to AC power only. It will not charge batteries.
WARNING: Hazardous Voltage The SureSine Inverter must be installed by a qualified technician in accordance with the electrical regulations of the country of installation.
CAUTION: This guide must be used with the full product manual that includes important information. Carefully read the SureSine Inverter product manual for all specifications, safety, regulatory and warranty information, and for all required instructions on installation procedures, configuration, and operation.

In the Box:
Tools Required:
— #2 Philips Screwdriver
— 3/16 (5 mm) & 1/8″ (3.8 mm) Flathead Screwdriver
— Drill with a 1/8″ (3.8 mm) bit
— Multimeter
— Crimping Tool
— Wrench
Minimum Clearance Requirements:
WARNING: Risk of Fire Do not install over an easily combustible surface, since the heat sink may get hot under certain operating conditions.
CAUTION: Burn Hazard Place in a location to avoid direct contact.
CAUTION: Equipment Damage
Do not expose the SureSine to weather. Locate in a dry, protected area to prevent equipment damage. Ensure the minimum clearance requirements are followed to provide adequate ventilation and prevent the unit from overheating.
WARNING: Risk of Fire
All over-current protection devices and wiring must be sized properly, in accordance with US National Electric Code (NEC) or the country of installation’s local regulations.
WARNING: Explosion Hazard
Never install the SureSine in an enclosure with vented/flooded batteries. Battery fumes are flammable and will corrode and destroy the SureSine circuits. Ensure sufficient ventilation.
WARNING: Shock Hazard
Fuses, single-pole circuit breakers or single-pole disconnect switches should NEVER open grounded system conductors. This could create a shock hazard that could be fatal to personnel and/or damage the equipment.
IMPORTANT: Neutral-Ground Bond
The AC Neutral of the 120 Vac/ 60 Hz models is bonded to the inverter frame internally fromthe factory as required for UL safety requirements.
The AC Neutral of the 127 V, 230 V, and 240 V models is floating (not bonded to the inverter frame). If a neutral-ground bond is required an internal neutral-ground jumper wire (included) can be used to connect the neutral terminal to the grounded chassis.
Consult Section 2.8.4 of the manual for additional information.
CAUTION: Equipment Damage
Ensure the AC loads do not exceed the continuous and surge power ratings.
Mounting:
Step 1: Choose mounting location
A)Determine how and where the inverter will be mounted.
B)Ensure the inverter is protected from sun, rain, and dust.
Step 2: Wiring accessibility and air flow clearance
A) Plan and confirm wire routing-access.
B)Verify that the mounting screws will not penetrate wires or other objects located on the opposite side of the surface.
C) Verify that there is at least 6″ of space around the unit.
Step 3: Mark and drill holes
A)Place the inverter on the wall where the unit will be mounted.
B)With a pencil or pen, mark the center of each keyhole slot; two (2) on top and two (2) on the bottom.
C)Remove the inverter and drill four (4) 1/8″ (3.175 mm) holes where the marks were made.
Step 4: Secure the inverter
A)Place the SureSine onto the surface and align the keyhole slots with the four (4) pilot holes.
B)Use the four (4) #10 screws (included) to secure the SureSine to the surface.
For optimal ventilation and cooling, mount in portrait style orientation.
